Moving target indication (MTI) is a mode of operation of a radar to discriminate a target against clutter.
In contrast to another mode, stationary target indication, it takes advantage of the fact that the target moves with respect to stationary clutter. The most common approach takes advantage of the Doppler effect. For a given sequence of radar pulses, the moving target will change its distance from the radar system. Therefore the phase of the radar reflection that returns from the target will be different for successive pulses. This differs from a stationary target (or clutter) which will cause the reflected pulses to arrive at the same phase shift.
Radar MTI may be specialized in terms of the type of clutter and environment: airborne MTI (AMTI), ground MTI (GMTI), etc., or may be combined mode: stationary and moving target indication (SMTI).

Famous quotes containing the words moving, target and/or indication:
“A self is, by its very essence, a being with a past. One must look lengthwise backwards in the stream of time in order to see the self, or its shadow, now moving with the stream, now eddying in the currents from bank to bank of its channel, and now strenuously straining onwards in the pursuit of its chosen good.”
—Josiah Royce (1855–1916)
“All of women’s aspirations—whether for education, work, or any form of self-determination—ultimately rest on their ability to decide whether and when to bear children. For this reason, reproductive freedom has always been the most popular item in each of the successive feminist agendas—and the most heavily assaulted target of each backlash.”
—Susan Faludi (20th century)
“Television could perform a great service in mass education, but there’s no indication its sponsors have anything like this on their minds.”
—Tallulah Bankhead (1903–1968)
